The Next Generation

• Large prompt background when pions and muons are produced

• Signal muon-to-electron conversion occurs with a delay ⇒ Pulse primary beam to separate prompt backgrounds

• O(1 ¹s) between pulses
• Muonic atom lifetimes vary due to nuclear muon capture
• Al: 880 ns
• Ti: 330 ns
• Au: 73 ns

• New designs contain built-in background rejection
